Here s an easy way using jQuery   var scrollbarWidth   jQuery  div withScrollBar   get 0  scrollWidth - jQuery  div withScrollBar   width      Basically we subtract the scrollable width from the overall width and that should provide the scrollbar s width  Of course  you d want to cache the jQuery  div withScrollBar   selection so you re not doing that part twice
